The wound pipe machine is a widely used product that replaces the metal springs of traditional hose protection. wound pipe machines are generally made of materials such as nylon or polypropylene. Equipment for the production of wound pipe includes plastic extruders, sheath winding machines, and vulcanizing tanks. Each of them has a different task and is prone to different faults, so do you know how to troubleshoot problems on a wound pipe machine?

Here is the content list:

•Extruder fault analysis

•Analysis and treatment of abnormal noise

•Dealing with machine wear and tear

Extruder fault analysis

In a wound pipe machine, the extruder is usually referred to as the main machine, while the spiral wound pipe machine plastic extruder and its accompanying subsequent equipment are referred to as the auxiliary machine. After more than 100 years of development, spiral wound pipe machine plastic extruders have been derived from the original single screw, multi-screw, and even screwless models. Extruders (main machines) can form various plastic extrusion and molding lines to produce various plastic products. Therefore, winding pipe machine plastic extruders are one of the widely used machines in the plastics processing industry, both now and in the future.

Analysis and treatment of abnormal noise

When the wound pipe machine is working, noise such as occurs in the reducer may be caused by damaged bearings or poor lubrication, or it may be caused by worn gears, improper installation, and adjustment or poor meshing. It can be solved by replacing the bearings, improving lubrication, replacing the gears, or adjusting the gear meshing condition. If the noise is a sharp scraping sound, you should consider the possibility that the position of the extruder barrel of the wound pipe machine is skewed, causing the head of the shaft and the drive sleeve to scrape. Can be solved by adjusting the barrel. If the noise is from the barrel, it is possible that the screw is bending and sweeping or the set temperature is too low causing excessive friction of solid particles. This can be dealt with by straightening the screw or increasing the set temperature.

The main causes of extruder wear

Normal wear on the extruder screw and barrel of the wound pipe machine occurs mainly in the charging and metering zones, mainly caused by dry friction between the sliced particles and the metal surface. Unusual wear on the extruder screw and barrel of a wound pipe machine can occur when the screw is ringed and jammed by a foreign object. are very difficult to repair. The barrel is designed in principle to ensure a longer service life than the screw, and for normal barrel wear, it is generally no longer repaired, often by repairing the screw threads to restore the radial clearance within the barrel of thewound pipe machine extruder in conjunction with the outer diameter of the screw.

This is the analysis of extruder faults in the wound pipe machine. If you need a wound pipe machine, you can consider our cost-effective products. The materials used by EAGLE Company are non-toxic and tasteless, perfect after-sales service, you can have no worries.
